OGLE-2018-BLG-0298L b
OGLE-2018-BLG-0298L b is a Neptune-like planet orbiting OGLE-2018-BLG-0298L in the constellation Ophiuchus. It lies about 21,331 light-years from Earth and was discovered in 2022 using the microlensing method.
Is OGLE-2018-BLG-0298L b in the Habitable Zone?
The position of OGLE-2018-BLG-0298L b relative to the habitable zone of OGLE-2018-BLG-0298L cannot be precisely determined from the available orbital data.
Orbit and Year Length
OGLE-2018-BLG-0298L b orbits at an average distance of 2.860 AU.
How Was OGLE-2018-BLG-0298L b Discovered?
OGLE-2018-BLG-0298L b was discovered in 2022 using the microlensing method, with observations from OGLE.
Gravitational microlensing detects a planet when its host star passes in front of a more distant background star, and the planet's gravity adds a brief, telltale spike to the magnified starlight. It can find planets thousands of light-years away.
How Far Away Is OGLE-2018-BLG-0298L b?
OGLE-2018-BLG-0298L b is 21,330.6 light-years (6,540.0 parsecs) from Earth. Light arriving here tonight left the planet about 21,331 years ago. A probe traveling at the speed of Voyager 1 — about 17 km/s, the fastest outbound spacecraft ever launched — would need roughly 375,418,560 years to make the journey.
